NUT-LOCK.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed August 27, 1906. Serial N0- 332,146.

To all whom 'it may concern:

Be it known that I, HARRY H. HENsoN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Nut-Locks,

of which the following is a specification.

My invention relates to a nut lock particularly adapted to lock nuts upon the end of axle spindles to retain the vehicle wheels upon said spindles.

Further objects and advantages of the invention will be set forth in the detailed description which now fol lows In the accompanying drawingFigure 1 is a view partly in elevation and partly in section of an axle spindle and illustrating a nut locked thereon by my improved nut lock, Fig. 2 is an end elevation of the parts illustrated in Fig. 1, and, Fig. 3 is a view partly in section and partly in elevation of a wrench adapted to be used in conjunction with the device.

Like numerals designate corresponding parts in all of the figures of the drawing? Referring to the drawing, the numeral 5 designates the axle spindle. This axle spindle is threaded as at 6 for the reception of a nut 7 of the usual and well known character used in connection with the axle spindles of vehicles. The end of the spindle has an opening 8 formed therein, said opening being angular in cross section. The web 9 which forms the front face of the nut also has an angular opening 10 formed therethrough. A sliding bolt 11 which is angular in cross section is disposed within the opening 8. Bearing between the inner end of the opening 8 and the end of the bolt 11 is a spring 12. The outer end of the bolt is reduced as at 13 and fits the opening 10 formed in the web 9 of the nut 7.

A wrench 14 which comprises a handle 15 and a body portion 16 is used in connection with this nut lock. The body portion 16 of the wrench is adapted to fit the nut in the usual manner. The only difference between this wrench and the wrenches usually used being the provision of a round lug 17 which projects from the base wall 18 of the Wrench.

With the parts in the position illustrated in Fig. 1, the spring 12 forces the sliding bolt outwardly and holds the angular portion 13 of said bolt into the angular opening 10 of the nut. Since the body portion 11 of the bolt is angular in cross section and since the opening 8 in which it slides, is also angular in cross section, it follows that this bolt is held against turning and will in turn hold the nut 7 against turning. If it be desired to remove the nut, the wrench is fitted upon said nut, the round lug 17 pressing the end 13 of the bolt 11 out of engagement with the opening 10, thereby permitting the nut to be turned. The front wall of the spindle adjacent the opening 8 is spun over as at 20 to prevent the bolt 11 from being forced out of the opening 8 after the nut 7 has been removed.

From the foregoing description, it will be seen that simple and efficient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purpose for which they areintended, it is to be understood that my invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

What I claim, is:

The combination with an axle spindle, of a nut adapted to be threaded upon said axle spindle, said nut having a web which extends across the end of the axle and said web having an angular opening formed therein, a bolt angular in cross section and having a reduced angular outer end which is adapted to enter the angular recess of the web of the nut, a spring located in the opening of the spindle behind the bolt and normally tending to force said bolt outward, and a web 20 spun over the outer end of the opening of the axle spindle to prevent the passage of the bolt therefrom.

In testimony whereof I afliX my signature in presence of two witnesses.

HARRY H. HENSON.
